This paper provides a natural deduction system for Partially Commutative Intuitionistic Multiplicative Linear Logic (PCIMLL) and establishes its normalisation and subformula property. Such a system in- volves both commutative and non commutative connectives and deals with context that are series-parallel multisets of formulae. This calcu- lus is the extension of the one introduced by de Groote presented by the second order for modelling Petri net execution, with a full entropy which allow order to be relaxed into any suborder — as opposed to the Non Commutative Logic of Abrusci and Ruet. Our result also includes, as a special case, the normalisation of natural deduction the Lambek calculus with product, which is unsurprising but yet unproved. Up to now PCIMLL with full entropy had no natural deduction. In particular for linguistic applications, such a syntax is much welcome to construct semantic representations from syntactic analyses. 1 Presentation Non commutative logics arise naturally both in the mathematical perspective and in the modelling of some real world phenomena. Mathematically non com- mutativity is a natural both from the truth valued semantics viewpoint (phase semantics, based on monoids which can be non commutative) and from a syn- tactical one (sequent calculus with sequences rather than sets of formulae, proof nets which can have well bracketed axiom links). Non commutativity also ap- pears from real world applications such as concurrency theory, like concurrent execution of Petri net, and in our favourite application, computational linguistic, and this goes back to the fifties and the apparition of the Lambek calculus. We first give a brief presentation of non commutative logics and then stress their interest for concurrency and computational linguistics. Non commutative linear logics Linear logic (6) oered a logical view of the Lam- bek calculus (9) and non commutative calculi. During many years, the diculty was to integrate commutative connective and non commutative connectives. A first solution, without a term calculus, was Pomset Logic, now studied with extended sequent calculi callled Calculus of Structures (7).
